    Geometric morphometrics of the human cervical vertebrae: sexual and population variations
    (Journal of Anthropological Sciences, 2021) Palancar, Carlos A.; García Martínez, Daniel; Cáceres Monllor, David Antonio; Perea Pérez, Bernardo; Ferreira, María Teresa; Bastir, Markus
    This study aims to carry out the first geometric morphometric analysis of the 3D size and shape of the full series of cervical vertebrae delving into variability related to sex and population background. For this reason, we analyzed the cervical vertebrae of both males and females belonging to Europeans, Africans, and Greenland Inuit. We 3D-scanned a total of 219 cervical vertebrae of males and females of three different modern human populations (European, African, and Inuit). A minimum of 72 landmarks and curve semilandmarks were positioned in each of the 3D vertebral models. Landmark configurations were analyzed following the standards of 3D Geometric Morphometrics to test for size and shape differences related to sex or population variation. Results show that male cervical vertebrae are consistently larger than in females while no regular shape differences are observed between males and females in any of the populations. Sex differences in cervical lordosis are thus not supported at the skeletal level of the 3D shape. On the other hand, there is no evidence for population-specific differences in size while shape does vary considerably, possibly also in relation to eco-geographic factors of overall trunk shape. Cervical vertebrae in cold-adapted Inuit were consistently shorter than in Europeans and Africans. The cervical spine may show a different pattern than the thoracic and lumbar spine, which might be related to stronger integration with the cranium, head mobility, and soft-tissue dependence. Our findings suggest that morpho-functional interpretations of the cervical spine based on vertebral skeletal morphology requires caution.

    Paleogenetic evidence of a Pyrenean Neolithic family: Kinship, physical appearance and biogeography multidisciplinary analysis
    (Journal of Archeological Science, 2020) Lopes Gomes, Claudia Filipa; Gerard Remolins; López Parra, Ana María; Baeza Richer, Carlos; Guerrero, Diana; Palomo Díez, Sara; Labajo González, Elena; Perea Pérez, Bernardo; Arroyo Pardo, Eduardo
    One of the most important Neolithic necropolises in the north-east of the Iberian Peninsula is La Feixa del Moro (3975-3790 cal. BC), located at 1335 mamsl in the Pyrenees (Juberri, Sant Julia de Lòria, Andorra). Within the scarcity of multiple simultaneous Neolithic burials, the main importance of La Feixa del Moro lies in the fact that it is one of the very few cases to suggest a biological family burial, comprising two adults and a newborn baby. Accordingly, the purpose of the present work was the multidisciplinary interpretation of the necropolis in the Neolithic context of the Pyrenees, on a potential route between the Iberian Peninsula and Europe. Therefore, kinship and biogeographic analyses were performed, as well as external visible characteristics phenotyping. Our results suggest the possibility of a traditional nuclear family, pointing to a very probable relation between the newborn and both adults. First, two mitochondrial haplotypes and two lineages were determined: H1, for the presumable mother and newborn, and U5, for the presumed father. Second, regarding their physical appearance, they all had brown eyes, the adult female and the neonate had dark brown hair, while the adult male's hair was dark red-brown. Finally, it was possible to confirm the sex of two of the individuals, as the newborn baby gender was also confirmed by the High Troughoutput Sequencing analysis. The multidisciplinary analysis of the La Feixa del Moro burial place envisions a very probable familial burial. Not only does the genetic evidence point to biological kinship, but also the archaeological record indicates a habitational area surrounding the burial site. The similar artefacts and the care shown during the funerary ritual suggest a probable biological Neolithic family.
